DESCRIPTION
The hot wire tester will specify the material(diameter4mm，Ni77/Cr20±1) andUHeating the shaped electric heating wire with high current to the test temperature( 200℃ ～ 1250 ℃)1minAfterwards, to regulate the pressure(1.0N)Vertical burning test sample30sDetermine the fire hazard of electrical and electronic equipment products based on whether the test sample and bedding ignite or hold on for a certain period of time; Determination of ignition properties and ignition temperatures of solid insulation materials and other solid combustible materials (GWIT)Flammability and Flammability Index(GWFI).
FEATURES
The hot wire tester is suitable for research, production, and quality inspection departments of electrical and electronic products and their component parts such as lighting equipment, low-voltage appliances, household appliances, machine tool appliances, motors, power tools, electronic instruments, electrical instruments, information technology equipment, electrical affairs equipment, electrical connectors, and accessories. It is also suitable for industries such as insulation materials, engineering plastics, or other solid combustible materials.
